JOHN SHINN, OF PHILADELPHIA, PENNSYLVANIA.

CARDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 299,280, dated May 27,1884.

Application filed June :25, 1883.

To all whom it may concern Be it known that 1, JOHN SHINN, a citizen ofthe United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulImprovement in OardingMachines, of which the following is aspecification.

My invention belongs to machinery for carding fibers, vegetable oranimal. It relates to that part of the machine for removing or doffingthe fibers from that part of the machine known as the doffer-cylinder.Previous to my invention the fibers have been removed from thedofi'er-cylinder either by a comb having a reciprocating motion, or bytwo rollers, as is shown and described in Patent N 0. 24,092, May 24,1859. A reciprocating comb is objectionable when it is desired to runthe doifer-cylinder at such a speed as will deliver a light sliver, andat the same time deliver the quantity of fibers the machine is capableof carding. Doffing-rollers, as shown in Patent No. 24,092, May 24,1859, while being capable of doffing and delivering the sliver at anyspeed and in quan tity that the machine will card, have not come intogeneral use for the reason that they are not reliable. The objectionsare that, when the feed has stopped for any reason, when started up, therollers fail to catch the fibers at the start, and in some cases pressthe fibers into the wire on the dofi'er-cylinder, causing trouble and insome cases injury to the wire on the dotfer-eylinder.

My invention consists in the combination, with the doffer-cylinder anddoffing or delivery rollers, of a stationary comb to insure the removalof the fibers from the wire or teeth thereof, so that they may be caughtand delivered by the rollers, as will be hereinafter described,referring to the annexed draw- (No model.)

Similar letters of reference refer to like parts.

A represents the dofi'er-cylinder; B, the comb; D D, the doffing ordelivering rollers, and E E the cleaners or clearers.

The comb B is made of steel, in form the same as now used forreciprocating combs. The comb B is fixed stationary to the top cleaner,E, as shown in Fig. 1. In Fig. 2 it is fixed to a bar of wood or iron.section.) The comb B is set so that the teeth of the comb will lightlypress the cardwire or teeth on the doffer-cylinder. The top roller D iscovered with flannel and leather. The bottom roller D is a plain ironone.

The cleaners E E are made of wood. That part which touches the rollersis covered with woolen flannel.

Fig. II shows a modified arrangement of the rollers. His a dofferorcarrier roller, and is covered the same as the toproller D.

The operation of my improvement is as follows: The doffcr'cylinder A androllers D D are driven by gears or bands, as is usual on cards that aredoffed by rollers. They move in direction indicated by the arrows. Therollers D D'should be speeded to deliver the sliver faster than thedoffer A-say one in ten-that is, for ten inches of sliver delivered bythe doifer A the rollers D D will deliver eleven inches,giving therollers draft. The abovedescribed gears and draft are no part of myinvention; but they were found to work well in operating thedoffing-rollers in Patent No. 24,092, of May 24,1859.

The comb B is set so that the fibers on the wire of the doffer-cylinderwill be caught on the teeth of the comb, and as they accumulate thereonwill be drawn between the rollers D D, and delivered in a thin sliver,with the fibers all straight, and not wavy, as with the reciprocatingcomb.

The object of the cleaners is to clean the rollers and prevent them fromlapping, in a manner as is well known in cotton carding and drawingmachinery.

My improvement may be applied to woolcondenser cards, and when so usedthe clean- .ers E E may not be required, as the rub-roll- (Shown inerswill keep the doffing-ro1lers clean and pre- 2.
